Definitions
- Today's lens antenna covers are generally manufactured by hand lay-up FRP process.
- the hand lay-up process not only takes a long time and has low production efficiency, but also requires bonding of special-shaped structures, which makes the mechanical structure fragile. It will exist when working outdoors in bad weather, such as when a typhoon comes. Big risk.
- the cost of hand-laying FRP lens radomes is very expensive, and the hand-laying process can easily lead to uneven wall thickness of the radome, resulting in poor electrical performance.
- the special-shaped structure easily makes the pultrusion process complicated or impossible to manufacture.
- the mold cost of a single outer cover is more than 500,000 yuan, and the cost of a single outer cover is also more than 3,000 yuan, making the overall cost of the antenna very high and not cost-effective. .
- the radome is composed of two parts, one is a semicircular structure and the other is a U-shaped structure. First, put these two parts together. An outer cover is formed by bonding and connecting with rivets and glue, and then the outer cover and the upper and lower end caps form the outer cover of the antenna. Although this arrangement can reduce manufacturing difficulty and cost, it still does not solve the problem of unreliable structure. If used outdoors for a long time, the lens material will easily fall off, and the waterproofing of the entire antenna will easily fail, making the antenna unable to work.
- a new type of lens antenna housing including:
- An outer cover which includes an outer cover main body with openings on both sides and a lower end cover disposed at one side opening of the outer cover main body, and the outer cover main body and the lower end cover are integrally formed;
- providing a plurality of first reinforcing ribs can further increase the strength of the outer cover and extend its service life.
- the outer cover is integrally formed of plastic using a rotational molding process.
- the outer cover is made of polyethylene material.
- an anti-ultraviolet UV agent is added to the polyethylene.
- the wall thickness of the outer cover is 2 to 20 mm.
- the outer cover is integrally formed of plastic using a blow molding process.
- a plurality of second reinforcing ribs are provided on the support partition.
- the support partition is integrally formed by a rotational molding process.
- the support partition is made of plastic or fiberglass and is integrally formed using a pultrusion process.
- the support partition is integrally formed using the rotational molding process or the pultrusion process. Not only is the mold manufacturing simple, but the mold cost and single product price are also low.
- the upper end cover is integrally formed by blister molding, rotational molding or injection molding.
- the upper end cap made by the blister process has the advantages of low price and high production efficiency.
- this application also provides an antenna device, including the above-mentioned lens antenna cover, array antenna and lens, wherein:
- the lens is arranged inside the outer cover, and the lower end cap is used to support the lens.
- the new lens antenna housing and antenna device of the present application have the following beneficial effects:
- the lens antenna cover of this application is integrally formed by the main body of the cover and the lower end cover.
- the integrated structure is not only waterproof, but also ensures that its strength can support the lens material installed in the cover to avoid prolonged outdoor use. There is no risk of lens material falling off after use.
- the structure is stable and reliable.
- the rotational molding process can not only produce a large-sized housing to meet the size requirements of the cover, but also has a low manufacturing cost. Its mold fee and single product price are 15% of those of other processes. -20%.
- the outer cover made by rotational molding process has the characteristics of high load-bearing strength, strong pressure resistance, and wear resistance.
- the dielectric constant of the polyethylene material of the lens antenna cover of the present application is low (around 2.3), the dielectric loss is also small, so it is suitable for manufacturing the antenna cover.
- an anti-UV agent added to the polyethylene, the aging problem of the cover caused by ultraviolet radiation when used outdoors for a long time can be avoided, thereby extending the service life of the cover.
- the support partition of the lens antenna cover of this application is integrally formed using a rotational molding process or a pultrusion process. Not only is the mold manufacturing simple, but the mold cost and single product price are also low.
- the lens antenna cover of this application uses an upper end cover made by a blister process, which has the advantages of low price and high production efficiency.
- Figure 2 is a schematic structural diagram of the lens antenna cover of the present application after the upper end cover is hidden;
- Figure 3 is a schematic structural diagram of the outer cover of the lens antenna cover of the present application.
- Figure 4 is a schematic structural diagram of Figure 3 from another perspective
- Figure 5 is a schematic structural diagram of the support partition in the lens antenna housing of the present application.
- FIG. 7 is an exploded schematic diagram of the antenna device of the present application.
- Figure 8 is a schematic structural diagram of Figure 7 from another perspective
- FIG. 9 is a schematic structural diagram of the antenna device of the present application.
- Figure 12 is a schematic structural diagram of an antenna device according to another embodiment of the present application.
- this application first provides a new type of lens antenna housing 1, which includes a housing 11, a supporting partition 12 and an upper end cover 13.
- the housing 11 includes a housing body 111 with openings on both sides and a The lower end cover 112 at the side opening, the cover main body 111 and the lower end cover 112 are integrally formed.
- the support partition 12 is arranged inside the outer cover 11 to support and strengthen the outer cover 11 .
- the upper end cap 13 is provided at the other opening of the outer cover body 111 to seal the outer cover 11 .
- the outer cover 11 is integrally formed of plastic using a rotational molding process.
- it can also be integrally molded from plastic using a blow molding process, which is not limited here.
- the outer cover 11 is made of polyethylene (polyethylene, PE for short) material. Since the polyethylene (PE) material has a low dielectric constant (around 2.3) and a small dielectric loss, it is suitable for manufacturing antenna covers.
- the polyethylene (PE) may be high density polyethylene (HDPE) or low density polyethylene (LDPE) or linear low density polyethylene (LLDPE).
- the wall thickness of the outer cover 11 is between 2 and 20 mm.
- the support partition 12 can also be integrally formed from plastic or fiberglass using a pultrusion process, which is not limited here.
- the lens 2 is an electromagnetic lens
- the array antenna 3 is a high-frequency 4-beam electrically adjustable antenna, and each beam is independently electrically adjustable.
- Lens antenna cover 1 of the present application is integrally formed by the cover main body 111 and the lower end cover 112.
- the integrated structure is not only waterproof but also ensures its strength. It can support the lens material installed in the outer cover 11 to avoid the risk of the lens material falling off after long-term outdoor use, and has a stable structure and high reliability.
